Vehicle-mounted ex-situ direct thermal desorption system and application method thereof

Abstract

The invention discloses a vehicle-mounted ex-situ direct thermal desorption system and an application method thereof. The system comprises a transport vehicle that comprises a bearing bottom plate; the system further comprises a feeding device, a drying kiln device, a flue gas treatment device and a discharging device. The drying kiln equipment and the flue gas treatment equipment are fixedly installed on the bearing bottom plate, the discharging end of the feeding equipment is connected with the feeding end of the drying kiln equipment, the gas outlet end of the drying kiln equipment is connected with the gas inlet end of the flue gas treatment equipment, and the discharging end of the drying kiln equipment and the discharging end of the flue gas treatment equipment are both connected with the feeding end of the discharging equipment. According to the vehicle-mounted ex-situ direct thermal desorption system, other devices except the feeding device and the discharging device are all arranged on the flat car and are installed and debugged before production, and the problems that civil engineering, installation and debugging need to be conducted on a project site, and the disassembling and assembling period is long are solved. According to the system, plug and play of a project site is completely achieved, and large cost can be saved for a repair project with small earthwork volume and low total price.

Description

technical field [0001] The invention relates to the field of soil remediation equipment, in particular to a vehicle-mounted ex-situ direct thermal desorption system and an application method thereof. Background technique [0002] Thermal desorption is also called thermal desorption. As a non-combustion technology, the pollutants can be treated in a wide range, the equipment can be moved, and the soil can be reused after restoration. Especially for chlorine-containing organic substances, the treatment method of non-oxidative combustion can avoid dioxins. The generation of Ying is widely used in the remediation of soil contaminated by organic pollutants. [0003] Thermal desorption technology refers to heating the organic pollutants in the soil to a sufficient temperature through direct or indirect heat exchange under vacuum conditions or when the carrier gas is introduced, so that the organic pollutants can be volatilized or separated from the polluted medium. The process of...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a vehicle-mounted ex-situ direct thermal desorption system for small polluted sites with short restoration period and low restoration cost. The system can avoid civil foundation, save on-site installation, commissioning and disassembly time, and shorten the restoration period. and other advantages, and also provides an application method of a vehicle-mounted ex-situ direct thermal desorption system, which can at least solve one of the above-mentioned problems
